LAWRENCE REID, OF NEW YORK, AND JOHN ROGERS, OF BROOKLYN, N. Y.

IMPROVED SOAP.

Specification forming part of Letters Patent No. 44,457, dated September27, 1864.

To all whom it may concern:

Be it known that we, LAWRENCE REID, of the city, county, and State ofNew York, and JOHN-ROGERS, of Brooklyn, King county, and State of NewYork, have invented a new and useful Composition and Mode of PreparingSoap; and we do hereby declare that the within is a full and exactdescription of the same.

Though diflerent proportions maybe used to the taste of customers, andto accommodate the manufacturers in the raw materials from which theyprepare soaps, we will here state the mode of preparing our compositionsand the proportions which we prefer.

Having our soapprepared from good raw materials-as fat, caustic sodalye, a little palmoil, and all well boiled and saponitied in salt andalkaline lyes-it is retained by heat in the fluid form and fit to mold.We then prepare our solution of glue or gelatine, either as weobtain itin making bone-glue or skin-glue or gelatine from any source, or by thesolution of glue or gelatine in hot water at the boilingpoint, or verynear it-say for every hundred pounds of melted hot soap take six poundsof good glue or a solution of gelatine or glue, as before described,equivalent to that proportion of dry glue, all being in a hot state,near 212 and perfectly fluid. Mix both together and add at the same timethree pounds of causticsoda lye of the'strength of twenty-five per cent.by Baums hydrometer, this last also near the boiling temperature.Continue to mix, and immediately mold, or, better, to suit the custom ofsoap-makers, the mixture may be made in the usual mold, taking the sameprecautions in regard to a thorough and complete incorporation of thedifl'erent materials, and that they be all at the boiling temperature ornear it previous to mixing. Though we have named these proportions asmaking a powerful, elegant, and useful family soap, it \vill'be obviousto soapmakers that they may be much varied, increasing the productandintensifying the quality of soap by the relative quantity of glue orgelatine and caustic soda'employed from twenty-four to cent per cent. Inthe quantities used, as above described, the increase in weight istwenty-four per cent.

What we claim as our invention, and desire to secure by Letters Patent,is-

lheincorporatingofgelatineorglue as made previous to drying in a freshstate, or a solution from the dry articles in suflicient quantity, asfrom five to fifteen per cent. of glue, and a proportion of caustic sodaby from three to nine per cent. of the specific gravity of 25 by Banmshydrometer, the whole forming a uniform mass, possessing the trebleattraction of gelatine, caustic soda, and ordinary soap for dirt, andthus increasing quantity and improving quality, all donein the mannerset forth in this specification.
